If the diameter is 16 inches, then its radius is half that, r = 8.
Answer:
y=1/2x-1
Step-by-step explanation:
The point of (0, -1) goes up 1 and 2 over to get to the next dot and the y-intercept is (0,-1) because that's where it hits the y.
Her first rate was faster. The 10 minutes with a change in elevation of -200ft.
In order to solve this you need to have the same minutes. In this problem, I just simply took the 10 minutes and the -200ft and doubled it. Now both rates have 20 minutes. The first rate would have gone -400ft in 20 minutes while the second rate was only -300ft in 20 minutes. I hope this wasn't confusing, and I'm willing to explain more.
Answer:
<h3>
f(x) = 2(x - 6)² - 3 </h3>
Step-by-step explanation:
f(x) = a(x - h)² + k ← vertex form of parabola equation with vertex (h, k)
So:
f(x) = a(x - 6)² + (-3)
f(x) = a(x - 6)² - 3 ← vertex form of our parabola equation
Parabola goes through (8, 5) so if x=8 then f(x)=5
5 = a(8-6)² - 3
5 +3 = a(2)² - 3 +3
8 = 4a
a = 2
That means, the equation of a parabola with vertex (6, -3) and passing through the point (8, 5):
f(x) = 2(x - 6)² - 3
First, take the GCF (greatest common factor) of the expression. This means, if the two values can be divided by the same thing, then divide. The problem is now in its simplest form because there are no more GCFs and it is factored completely.
8p - 12pq
(8p / 4p) - (12pq / 4p)
4p (2 - 3q)
Hope this helps!
